Abstract: PURPOSE:To easily and continuously change a compressor rate and a compressing operation range by providing a differential amplifier circuit which amplifies the difference between the output of a multiplier circuit and the outputs of a receiving line pilot signal and a main signal current, and sends a transmission line pilot signal and main signal current. CONSTITUTION:A differential amplifier circuit 1 which amplifies the difference between the output of a multiplier circuit 5 and the outputs of receiving line pilot signal and main signal current, and sends a transmission line pilot signal and main signal current is provided. This automatic gain controlling circuit compresses level fluctuation by feeding back the product of an output voltage passed through a band-pass filter 2, rectifying smoothing circuit 3, and exponential function circuit 4 and another output voltage VOUT obtained by the multiplier circuit 5. When the index of the exponential function circuit 4 and amplification factor of the amplifier 1 are respectively represented by (x) and mu(>>1), an automatic gain control circuit of 1/(x+1) in regulating ratio is realized. Namely, when the index (x) of the exponential function circuit 4 is changed, the compression rate can freely be changed.

Abstract: PURPOSE:To lower loading to an internal combustion engine at the time of idling by controlling a transfer gear transmitting driving force to wheels to be neutral when the shift lever of a transmission is actuated to a neutral position. CONSTITUTION:A power unit for a vehicle is equipped with a transverse internal combustion engine. In this case, a transmission 6 is provided by which gear shifting is actuated through the actuation of a shift lever 70. In addition, a transfer gear (auxiliary transmission section) 50 transmitting driving force to wheels and an actuator 72 actuating the transfer gear 50 are also provided respectively. Furthermore, a transfer gear switch-over section 74 is provided too, which causes the transfer gear 50 to make switch-over between a high range and a low range. In this case, the actuator 72 is drivingly so controlled by a control section 68 as to make the transfer gear natural when the shift lever 7 is actuated to a neutral position.
